I'm trying to take off my old faucet and replace it with a new one in
my bathroom's vanity. I had no problem shutting off the cold water
valve, but the hot one is giving me a hard time. I have about 98-99%
turned off and water still comes out of the faucet..albeit..its small
steady and solid..its not dripping. I applied W40 a couple of times,
waited and still can't shut it off completely. I am trying to avoid
using my main shutoff just for this and was wondering if there
anything else i can do. Would just taking off the handle help? Hate to
call a plumber for a small yet nagging situation. Thanks

I am not sure why you are trying to avoid using the "main shutoff valve",
and I am not sure if by "main shutoff valve" you mean the water shutoff
valve outside at the street or the "main shutoff valve" near where the water
comes into your home.

Sometimes, if the "main shutoff valve" doesn't completely turn off the
water, you can turn it off as much as possible, then open all the valves in
all the sinks and tubs etc and leave them open while you change the hot
water valve for the bathroom. But having everything else open, the pressure
drops in the system and you may be able to get whatever small flow there is
to only come out in the sinks, outside faucet, etc. that are below the level
of the bathroom vanity that you are working on. And, if you replace the
bathroom vanity hot water valve with another screw-on type (if that is what
happens to be there), or you replace it with a shark-fitting slip-on type
that requires no soldering, you can probably change out the hot water valve
that way. Then go ahead and do the work on the faucet change.

Good luck.
